Hi mecax... we run javacv in myrobotlab...

You would be interested in following this post, where another user is trying to get it working :

If you want to try with latest version :

1) delete the old myrobotlab folder where you installed it

2) delte the .repo folder which is in the main folder of your raspi ( if you can t see it, use ls -a command )

3) you should follow this till step 5 of this guide, it will install the opencv dependencies, like if you are going to recompile it, but you 'll stop at step 5 :

4) make a new, shiny folder and put the "latest jar" in : http://mrl-bucket-01.s3.amazonaws.com/myrobotlab.jar

5) install opencv service using runtime tab

6) Run it and hit the capture button

Hope it helps, let us know
